I signed up kbin.social but have since decided to go all in on Lemmy. I’ve tried all day to delete my account on kbin but it won’t let me. Once I click the delete confirmation pop up it simply reloads the feed and keeps your account.
Be warned. Currently you have no control over your data there. I think that settles it for me. I won’t be using that service again.
The other point is, how do you know which instances to go after to delete any content anyways? I think there is a way to see a list of federated servers, but there’s no way to know which has your data.
In theory you could send a takedown request to each of them, but that doesn’t seem helpful
